Extracted text: Question 4 The radius and the length of a cylindrical metal are 5.00 cm and 20.00 cm at 25°C, respectively. After it absorbed 9000 J of heat, the temperature raises from 25°C to 85°C and its length expands to 20.02 cm. Then, the cylinder was immersed to the water covered with insulator. The water initial temperature was 25°C and with mass 500 g. (Specific heat capacity of water is 4200 Jkg-1°C-)(Heat loss through the container and cover is negligible.) Determine (a) the volume of the cylinder at 85°C. (b) the heat capacity of the metal. (c) the equilibrium temperature of water after the cylindrical metal was immersed to the water.
